Today we are going to take a quick look at the WIO Terminal – The all-in-one Arduino solution from Seeedstudio. I received a review unit from Seeed to test and had a blast, so let’s get to it!
This feature loaded device includes a 2.4” display, Wi-Fi, MicroSD Card Reader, microphone, IR Emitter, and more. At the pricepoint of about $30, it is very affordable. Of all the Arduino device I have tested in the last few months, the WIO Terminal is easily the most impressive. I also think it will be the one that will be the most useful in the security testing field.
The WIO Terminal comes with a 2.4” Display built in. You can custom program the display using code, or display photos & images, or app output. You can program the buttons to scroll through the pictures or as input. You could use the WIO to play games, a simple one was pre-encoded on the device when I received it:
There are a lot of walk throughs and excellent code examples for every feature on the WIO Terminal Wiki. You can use any of the demo programs included in the WIO Terminal Wiki to get up and running quickly.
Like playing with the built in sensors:
You can store and save files to the MicroSD card, just format it as FAT32 (See the WIO Terminal Wiki for coding instructions).
You can display images or run a photo display show. Just use the photo display example, and drag and drop the photos to the SD card before you insert it into the WIO.
You could add sound using the built in buzzer. For “May the 4th” day, I had the WIO show an image of Darth Vader and play the Imperial March!
Another cool features of the WIO that I haven’t seen in other devices, is that it has built in magnets. This would allow you place the WIO on any metal surface and it will stick (your battery source would need to have magnest also). This could come in handy during a Red Team or Pentest, just snap the device onto a metal cabinet or inside a desk.
The built in microphone is a very interesting feature – you could program it to trigger on sound:
More capabilities are being added to the microphone library, so I am thinking at some point you would be able to record sound and save it on the internal SDCard. Of course, as a pentester, you wouldn’t want it to say “Microphone Reading”, lol.
Maybe something more like this:
The WIO can also connect to and act like a Raspberry Pi HAT!
Note: connector pins not included
The WIO Terminal can act as a USB client or host, I think this will be a great opportunity to turn the WIO into a HiD attack device, like a Rubber Ducky. Maybe at some point a USB ethernet connector would work with it, that would be very interesting. There were some coding issues with the HiD interface when I tried it out, but it is being worked on as we speak, and will be fixed soon.
Add in the ability to scan and attach to WiFi networks and you really have a complete programmable security tool. I did have trouble with the WiFi on my prototype board, but again, it seemed to be a coding issue and I am sure it will be taken care of soon.
It has two built in Grove connectors so you can attach a wide variety of sensors to it, greatly increasing its capabilities. Or use a WIO Link card to greatly increase its sensor connectivity:
I am really looking forward to delving deeper into this tool in the next few months. I think it has the capabilities to be a great addition to a Pentester’s toolkit, with the right programming and connected sensors. The WIO Terminal from Seeedstudio, Check it out!
